四、网络接口卡的翻译 Network Interface Card: The Bridge to Connect Devices to the Network Network Interface Card (NIC) is an important hardware component in computer networks. Its main function is to facilitate network communication and data transmission between different devices. By inserting into a slot on the motherboard, the network interface card allows computers and other devices to connect to the network. Its main functions include sending and receiving data packets, processing network protocols, and more. There are various types of network interface cards based on different transmission rates and interface types. Common types include Ethernet interface cards and fiber optic interface cards. Ethernet interface cards have been widely used in local area networks due to their high transmission speed and affordable price. On the other hand, fiber optic interface cards are widely used in long-distance transmission and high-speed networks due to their high bandwidth and strong anti-interference capabilities. Network Interface Cards are widely used in various scenarios, such as enterprise offices, school education, and home entertainment. In enterprises, network interface cards can help employees quickly access internal and external internet resources, improving work efficiency. In schools, students can use various online educational resources through network interface cards, promoting learning and communication. At home, network interface cards are the bridge connecting various smart devices within the home, making home life more convenient and intelligent.
